Alps Alpine Co., Ltd. — ~46 prefixes (MA-L)

Alps Alpine Co., Ltd. is a Japanese B2B electronics-component maker formed in 2019 from the merger of Alps Electric Co., Ltd. (founded 1948 as Kataoka Electric, renamed Alps Electric in 1964) and Alpine Electronics. Its OUI footprint is split across name variants that reflect that history: blocks registered to "ALPSALPINE CO,.LTD", the shorter "Alps Alpine", the legacy "ALPS ELECTRIC (USA), INC.", and "Alps Electric (Ireland) Ltd" — all the same corporate entity, totalling on the order of 46 MA-L (OUI-24) blocks. The registry addresses point to the company's Japanese manufacturing sites in Miyagi and Fukushima prefectures plus the former US (San Jose) and Irish (Cork) subsidiaries. Crucially, Alps Alpine is not a consumer-device brand: it sells wireless modules (Bluetooth/Wi-Fi combo, GNSS, UWB, V2X/cellular) into the automotive and IoT supply chains. An Alps Alpine OUI on a network therefore most often indicates an in-vehicle infotainment (IVI) head unit, telematics control unit, or a third-party device with an embedded Alps Alpine module, rather than a stand-alone Alps-branded gadget. Two related but distinct registrants share the name root and should not be conflated with the electronics vendor: Alpine Electronics Marketing, Inc. (one MA-M block) and Alpine Quantum Technologies GmbH in Austria (an MA-S block — an unrelated quantum-computing company). As with all OUI work, IEEE publishes no assignment dates, so any "date registered" on third-party MAC-lookup sites is a database artifact, not an IEEE fact.

IEEE assignment

~46 MA-L prefixes → ALPSALPINE CO,.LTD (also "Alps Alpine", legacy "ALPS ELECTRIC (USA), INC." and "Alps Electric (Ireland) Ltd") [Confirmed] — IEEE MA-L (cached registry: enrichment/registries/oui.csv); corroborated maclookup.app

Registry / block size

MA-L (24-bit OUI). One related entity (Alpine Electronics Marketing, Inc.) holds a single MA-M block; an unrelated namesake (Alpine Quantum Technologies GmbH) holds an MA-S block. [Confirmed] — IEEE MA-L / MA-M / MA-S (enrichment/registries/oui.csv, mam.csv, oui36.csv)

Prefix count

~46 MA-L blocks across the dual registration names (~42 under "ALPSALPINE CO,.LTD" + ~4 under "Alps Alpine"), reflecting pre/post-2019 merger naming; the two names are the same entity. Count is a current third-party snapshot and drifts. [Likely] — maclookup.app/vendors/alpsalpine-co-ltd, maclookup.app/vendors/alps-alpine. NOTE: IEEE publishes NO per-company total and NO assignment date.

Corporate history

founded 1948 (Kataoka Electric Co.), renamed Alps Electric Co., Ltd. 1964, merged with Alpine Electronics 2019 to form Alps Alpine Co., Ltd.; operates Components, Sensors & Communication, and Mobility divisions [Confirmed] — alpsalpine.com/e/company/history/

Device types

B2B wireless modules embedded in third-party hardware — automotive Bluetooth/Wi-Fi combo modules for IVI/navigation, GNSS modules and vehicle trackers, V2X and 5G/cellular automotive modules, UWB/digital-key (CCC) systems, and compact IoT/wearable Bluetooth modules (e.g. UGMZ2AA). On a network this most likely presents as an IVI head unit, telematics control unit, or an embedded Alps Alpine module.

Security context

CVE-2024-23961 (command injection) and CVE-2024-23960 (improper crypto signature verification) affect the Alpine Halo9 iLX-F509 IVI system (Alpine Electronics product, now part of Alps Alpine Group), disclosed at Pwn2Own Automotive 2024; CVE-2024-23961 was classified "shared risk" with accepted residual risk and no patch. The group reports an ISO/SAE 21434-certified CSMS across all 23 entities (March 2023). No known CVEs in the stand-alone wireless modules as of research date; threat surface is vehicle attack chains, not enterprise networking gear.

Analyst note

An Alps Alpine globally-administered OUI identifies genuine Alps Alpine silicon, but because these are embedded supplier modules the surrounding device is usually automotive or IoT hardware from another brand — treat the OUI as a component fingerprint, not a finished-product identity.
